Title: Drushless motor
Inventor: UJO TATSUZO
IPC: H02K29/00
Filed: 1986-12-19
Abstract: PURPOSE:To restrain the torque ripple of the title motor to a small value, by a method wherein at least three notched grooves or holes are provided on the rotor yoke side of a stator yoke with the pitch of electric phase angle of 60 deg.. CONSTITUTION:Three long holes 20 are provided radially on a stator yoke 1 with the interval of mechanical phase angle 15 deg. (electric angle 60 deg.) in the circumferential direction of the yoke 1. When a rotor yoke is rotated, flux is changed at the position of a long hole 20 at every times when one pole of a multi-pole magnet 7 passes through the positional area of the corresponding long hole 20 whereby cogging torque is generated. Such a change of flux is generated at the positions of respective poles of the magnet 7, therefore, the number of times when the change of torque or torque ripple is generated by one rotation of the rotor yoke 4 becomes three times of the number of poles of the magnet 7. Such a cogging torque is applied on the rotor yoke 4 as a loss torque whereby a generating torque may be removed and the torque ripple may be eliminated effectively.

Filed: 1996-11-13
Abstract: PROBLEM TO BE SOLVED: To obtain an infrared sensor by which infrared rays can be fast detected with high sensitivity by a method wherein one pair of heat sensing elements are installed side by side so as to arrange their polarities in order, the polarities at one element are connected electrically and heat information at the other element is converted into an electric signal so as to be processed. SOLUTION: One pair of Al electrodes 91a, 92b are formed on a silicon or magnesia substrate by a sputtering operation, a vapor deposition operation or the like, a ferroelectric thin film 93 is formed on them by a coating and drying operation or the like, and NiCr electrodes 91a, 92a whose shape and area are identical to those of the electrodes 91b, 92b are formed so as to be situated directly on the electrodes. The electrodes 91a, 91b and thin film 93 as well as the electrodes 92a, 92b and the thin film 93 form respective pyroelectric elements, and an infrared shielding film is formed on the latter pyroelectric element so as not to be irradiated with infrared rays. As a result, infrared rays are absorbed by the former pyroelectric element with good efficiency, and a signal corresponding to the intensity of the infrared rays is output.  Since the influence of the temperature change of an atmosphere appears in the same manner at both pyroelectric elements, the influence can be reduced when identical polarities of both pyroelectric elements are connected to each other.

Filed: 1995-11-21
Abstract: PROBLEM TO BE SOLVED: To lower the height of the whole of a sensor by integrally and coaxially attaching a vertical movement detection member with a slit disc by a common shaft having smaller diameter than the slit disc. SOLUTION: When a paper sheet passes through between respective paper guides 2, 2, a slit disc 3 is raised to a broken line position by pushed by the paper sheet. The slit disc 3 is integrated with a vertical movement disc 7 via a shaft 6 so that the vertical movement disc 7 is also raised to the broken line position by guided by a long hole 9 of a frame member 10 along with the raising of the slit disc 3. Raising of the vertical movement disc 7 is detected by a paper sheet presence/absence detection sensor 8. The slit disc 3 is rotated by contacted with the paper sheet passing therethrough so that the carrying speed of the paper sheet is detected by a paper sheet speed detection sensor 5 which measures the frequency of passing through a slit 4 formed in the slid disc 3.  The vertical movement disc 7 is smaller than the slit disc 3 in this case so that this device is lower than the conventional paper detection sensor, which has such a height as adding the diameter of the slit disc 3 to the height of the paper sheet presence/absence detection sensor 8, by the difference between the both discs.
